installing using this guide brings you to the latest version. tailscale.com/kb/1131/synology…

It’s a bit cleaner than installing via CLI directly.

If you have MagicDNS and HTTPS Certificates enabled in your Tailnet then you can also setup a user-defined script in DSM to run "tailscale configure synology-cert" every couple months. Then you can reach your Synology web GUI with a valid HTTPS cert using the tailnet FQDN.
